\qmltype GridLayout
! \instantiates QQuickGridLayout \inherits Item \inqmlmodule QtQuick.Layouts
Provides a way of dynamically arranging items in a grid.
To be able to use this type more efficiently, it is recommended that you understand the general mechanism of the Qt Quick Layouts module. Refer to \l{Qt Quick Layouts Overview} for more information.
If the GridLayout is resized, all items in the layout will be rearranged. It is similar to the widget-based QGridLayout. All visible children of the GridLayout element will belong to the layout. If you want a layout with just one row or one column, you can use the \l RowLayout or \l ColumnLayout. These offer a bit more convenient API, and improve readability.
By default items will be arranged according to the \l flow property. The default value of the \l flow property is GridLayout.LeftToRight
.
If the \l columns property is specified, it will be treated as a maximum limit of how many columns the layout can have, before the auto-positioning wraps back to the beginning of the next row. The \l columns property is only used when \l flow is GridLayout.LeftToRight
.
The \l rows property works in a similar way, but items are auto-positioned vertically. The \l rows property is only used when \l flow is GridLayout.TopToBottom
.
You can specify which cell you want an item to occupy by setting the \l{Layout::row}{Layout.row} and \l{Layout::column}{Layout.column} properties. You can also specify the row span or column span by setting the \l{Layout::rowSpan}{Layout.rowSpan} or \l{Layout::columnSpan}{Layout.columnSpan} properties.
Items in a GridLayout support these attached properties: \list \li \l{Layout::row}{Layout.row} \li \l{Layout::column}{Layout.column} \li \l{Layout::rowSpan}{Layout.rowSpan} \li \l{Layout::columnSpan}{Layout.columnSpan} \input layout.qdocinc attached-properties \endlist Read more about attached properties \l{QML Object Attributes}{here}. \sa RowLayout \sa ColumnLayout \sa StackLayout \sa Grid \sa {Qt Quick Layouts Overview}

Invalidates childItem and this layout. After a call to invalidate, the next call to retrieve e.g. sizeHint will be up-to date. This function will also call QQuickLayout::invalidate(0), to ensure that the parent layout is invalidated.

Qt::LayoutDirection QQuickGridLayoutBase::layoutDirection | ( | ) | const |
\qmlproperty enumeration GridLayout::layoutDirection
This property holds the layout direction of the grid layout - it controls whether items are laid out from left to right or right to left. If Qt.RightToLeft
is specified, left-aligned items will be right-aligned and right-aligned items will be left-aligned.
Possible values:
\value Qt.LeftToRight (default) Items are laid out from left to right. \value Qt.RightToLeft Items are laid out from right to left.
